Longest-lasting light bulbs

Most of the wear and tear that leads to burnouts in incandescent light bulbs is caused by turning them on and off, not by burning them.

[1] The bulb was originally at the Byers Opera House, and was installed by a stage-hand, Barry Burke, on September 21, 1908 (116 years ago) (1908-09-21), above the backstage door.

[citation needed] According to museum officials the lightbulb also lost power a number of times during the rolling blackouts of 2021.

[citation needed] The third longest lasting light bulb began operation in 1929-30 when BC Electric's Ruskin Generating Station (British Columbia Canada) commenced service.

The fourth-longest-lasting light bulb was above the back door of Gasnick Supply, a New York City hardware store on Second Avenue, between 52nd and 53rd Streets.

[citation needed] The fifth-longest-lasting light bulb was located in a fire house in Mangum, Oklahoma.

[6] The sixth-longest-lasting light bulb was in a washroom at the Martin & Newby Electrical Shop in Ipswich, England.

[7] The seventh-longest-lasting light bulb is located in the Cinema Napoleón in Río Chico, Venezuela.

Thomas Edison designed a bulb that was supposed to last forever, called the Eternal Light, and turned it on on October 22, 1929.
